Piston/Valve clearance

chickendreamer · 10-12-2002, 09:36 PM

Just a quick question here. E-303 cam, ford motorsport replacment lifters(FMS-M6500R302), ford motorsport replacment pushrods(FMS-M-6565-L302), 9.4 compression pistons(TRW-L2482F30), and 2.02 intake valves. If I run 1.7 ratio roller rockers will i have to worry about piston/valve clearance? All parts are shown in the www.summitracing.com catalogue.

Any input would be appreciated

you should have enough clearance but it is still good to always check. it is the only way to be sure. i'm running gt-40 alum heads with a custom ground cam w/ .525/.536 lift and a stock shortblock w/ no clearance issues.

Thanks for the reply bigblockcoupe. I'm ordering the parts from summit racing so I was trying to avoid the wrong part and have to send it back to them paying all the shipping fee's.
